I’d like to be able to use `` tags in posts to highlight bits of text, especially in quoted language. Is this something I should potentially take to markdown-it directly? ---

I think that Discourse could allow the `` HTML tag to be used in posts through a fairly small change to the core Discourse code. Getting markdown to support `mark` would be great too. I see a discussion on their forum about it here: [A proposal to support the \ tag with Markdown - Extensions - CommonMark Discussion](https://talk.commonmark.org/t/a-proposal-to-support-the-mark-tag-with-markdown/1981). ---

I went digging around the repo with `git grep markdown-it`, but got too many results to pinpoint where to propose a patch. ---

I recall that Discourse already passes through `` and ``. Those strike me as ~~vewy~~ very close to ``. ---

Are you just wanting to be able to use the `` HTML tag? If so, I think it just needs to get added to a list of allowed tags in the Discourse code. Someone from the dev team should know which file needs to get updated. ---

Yup, it’s `app/assets/javascripts/pretty-text/addon/allow-lister.js`. We should probably also make sure to ship some reasonable default CSS. ---

Can you share a screenshot of what `` would look like? We know what `` and `` look like.. ins and ~~del~~. Just trying to understand the goal. ---

```css background-color: yellow; ``` IIRC this is more or less as stands in many user-agent default styles. ---

I suppose that seems benign enough, and we have precedent in the form of `` and ``.. what do you think @sam @eviltrout? ---
